Randomized Controlled Trial Comparative Study
Prospective randomized clinical trial comparing laparoscopic cholecystectomy and hybrid natural orifice transluminal endoscopic surgery (NOTES) (NCT00835250).
Natural orifice transluminal endoscopic surgery (NOTES) is a technique still in experimental development whose safety and effectiveness call for assessment through clinical trials. In this paper we present a three-arm, noninferiority, prospective randomized clinical trial of 1 year duration comparing the vaginal and transumbilical approaches for transluminal endoscopic surgery with the conventional laparoscopic approach for elective cholecystectomy. ⋯ NOTES approaches using the flexible endoscope are not inferior in safety or effectiveness to conventional laparoscopy. The transumbilical approach with flexible endoscope is as effective and safe as the transvaginal approach and is a promising, single-incision approach.

Randomized Controlled Trial Comparative Study
Comparison of long-term outcome and quality of life after laparoscopic repair of incisional and ventral hernias with suture fixation with and without tacks: a prospective, randomized, controlled study.
Technique of mesh fixation in laparoscopic incisional hernia repair is a matter of debate. Literature is lacking in randomized trials comparing various methods of mesh fixation. This study was designed to compare the cost-effectiveness and long-term outcomes following the two methods of mesh fixation. ⋯ The suture fixation method is a cost-effective alternative to tacker fixation in patients with small- to medium-sized defects in laparoscopic incisional and ventral hernia repair. Suture fixation is better than tacker fixation in terms of early postoperative pain and return to activity. The two procedures are equally effective regarding the recurrence rates, complications, hospital stay, chronic pain, quality of life determinants, and patient satisfaction.
